Combination clamp and closure



Oct. 12, 1948. G. w. OAKES COMBINATION CLAMP AND CLOSURE Filed NOV. 1, 1944 R: w EA w Va m J w W w W M/ e G Patented Oct. 12, 1948 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to a clamp and closure for use in connection with a resilient end portion of a fluid conduit, to make a fluid-tight connection of the conduit with suitable means, and to close or seal said end portion to exclude air and also prevent leakage.

The clamp and closure of the present invention is one which may be combined advantageously with a fountain pen filling device disclosed in my copending application, Serial No. 531,733, filed April 19, 1944 now Patent #2,424,896, July 29, 1947.

The principal object of the invention is the provision of a device of the indicated character which enables the connection or coupling of elements in a fluid-tight manner so that fluid or liquid may be delivered from one element to another without waste resulting from leakage, and to close or seal the flow passage after delivery vof the fluid to prevent loss from evaporation or Fig. 3 is a view similar to Fig. 1 showing the 1 relation of parts for carrying out a filling operation.

Fig. 4 is a top plan view.

Fig. 5 is a sectional View taken on the line 5--5 of Fig. 1.

As shown in Figs. 1 to 5 inclusive, the clamp and closure is combined with a fountain pen filling device I applied to a bottle I I containing ink for filling fountain pens with ink by manipulating the device to produce a pumping action causing charges of ink to be delivered into the ink sack of a pen. This requires a fluid-tight connection of the outlet end of the filling device with the end section of the pen. After the filling operation the outlet end should be closed or sealed to prevent loss by evaporation and deterioration. The clamp and closure of the present invention serves adequately for this purpose in an effectual manner.

The clamp and closure includes a tubular body |2 having a transverse cut |3 part way through to provide an attaching section I4 and a clamping collar section l5. The section I5 is divided longitudinally to enable said section to be expanded and contracted. It is to be understood the body I2 is made of metal or other suitable material inherently resilient or having springiness. The section l5 at the division therein has apertured lugs l6 projecting laterally in spaced relation to each other. Nuts cooperate with the lugs l6, respectively, one of said nuts having a left thread and the other having a right thread. The nuts I! receive a screw [8 having left and right threads l9 and 20, respectively, adapted for threaded engagement with the threads of the nuts I1. By turning the screw [8 clockwise, as viewed in Figs. 1 and 3, the section IE will be caused to exert a clamping action and vice versa. A U-shape handle 2| has its apertured terminals secured to the opposite ends, respectively, of the screw |8 by suitable fastening elements 22. When the handle 2| is in the down position shown in Fig. l, the collar section 5 is released and in the up position shown in Fig. 3, the section I5 exerts the clamping action due to the fact that the screw l8 acting on the nuts presses the lugs l6 toward each other which is just the reverse of the operation when the handle 2| is moved into the down position.

A suitable closure member or stopper 23 is pivotally connected with the lugs |6, as at 24, so that the stopper may be swung between a closed and open posit-ion with respect to the outlet of the device I0.

In use, the tubular body I2 is placed around the outlet portion 25 of the filling device I0, which portion 25 is made wholly of resilient material such as rubber. Pins or screws 26 extend through the attaching section I4 into the portion 25 to secure the clamp with its closure in functioning position.

With the parts as shown in Fig. 1, the filling device is sealed or closed by the stopper 23, and the clamp is open. To fill a fountain pen, the stopper 23 may be moved to the open position, after which the writing end of the pen is inserted into the discharge end portion 25. The handle 2| is then moved to the up position as shown in Fig. 3, which will contract the section l5 about the portion 25, thereby making a fluid-tight connection of the filling operation. After the pen is filled, the handle is moved to the down position, allowing the, section l5 to expand, to release the to contract the clamping section for the purpose of compressing said conduit into a fluid-tightrcom nection with an article to be filled with fluid, and to allow the clamping section to expand to 'decompress the conduit for the purpose of releasing said article, said actuating means consisting of lugs on "said clamping section, 1a screw extending loosely through said lugs,;nuts on said lugs 'respectively, anda handle connected with said 2screw to rotate it -oausing the nuts to bear on the :lugs

to'contract theeclamping section and to withdraw the nuts to allow the clamping section to expand, for the purposes stated.

2. A device as set forth in claim 1, wherein said screw has left and right threads.

3. A device as set forth in claim. 1, and a closure member connected with said tubular part for movement between a closed position closing said conduit and an open position with respect thereto.
